水工混凝土结构施工期冻融破坏仿真模拟
Simulation study on freeze-thaw damage of hydraulic concrete in construction period
摘要
Abstract
During the long construction of hydraulic concrete, frost heave is one of the key factors which can result in concrete crack .Based on the previous studies and the analysis on freeze-thaw characteristics of concrete, new models for predicting elasticity coefficient and tensile strength with changes of age and freezing times were proposed. With the application of the 3-d finite element program, the process of frost heave damaging of concrete during construction period were simulated. Results showed that the calculated results had a good coincidence with the actual rules of crack. This research provides a useful reference for concrete projects.关键词
